DAtflPENlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 398,333, dated February 19, 1889.

Application filed February 16, 1888. Serial No. 264,215. (No model.)

To aZZ whom, it may concern.-

Be it known that I, JOSEPH M. JOHNSTON, a resident of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Dampening-Machines; and I do hereby declare the following to be a full, clear, and exv drawings, in which Figure 1 is a perspective view of my improved machine, and Fig. 2 is a longitudinal central section of the same.

Like letters refer to like parts.

In constructing my improved machine a body, a, is mounted on suitable legs, I), and tanks 0 a, one of which is formed in or se cured to each end of the body 0., these tanks being for the purpose of holding the water or otherfluid employed to dampen the collars or cuffs, and they are provided with suitable inlets and outlets for said fluid. The inside wall,

(Z, of each of these tanks is preferably inclinedinward, so that they extend toward each other; but they do not meet, a lateral slot or opening, 6, being left in the center of the body a of the machine, through which opening the collars or other articles pass as they come from the dampening-surfaces,hereinafter described.

Journaled in the bottom of the tank 0 is a roller, f, and mounted on the body a, over said roller f, is journaled in sliding bearings 7L a roller, 6, and parallel to and back of the roller 9 is another roller, 2', in stationary bearings 2', these two rollers being geared together by pinions,which allow a certain amount of move ment toward and from each other, for the purpose hereinafter set forth. In the bottom of the tank 0 is also journaled a roller, 70, and

over said roller 011 the frame a, in fixed bearings Z, is journaled a roller, Z, and front of said roller Z and parallel thereto is mounted in sliding hearings on another roller, m, the latter being adjusted toward the roller Z by a screw, .9, which bears at one end against a stationary bearing, 0, and passing at its opposite end through a screw-threaded hole, 3', so that by turning the screw the roll m may be adjusted to and from the roller Z. The rollers Z and m are geared together by pinions a, so that they will be properly driven.

Mounted on the body a on one side of the slot 6 in the fixed bearings o is a roller, 0, and on the other side of the slot 6 is mounted in sliding bearings 19 a similar roller, 19', which is geared by pinions g to the roller 0. To adjust the roller 19 toward the roller 0 by mov' ing the sliding bearings p, any suitable means may be employedsuch, for instance, as a screw, 0", which bears at one end against the stationary bearing '6, and passing at its opposite end through a screw-threaded hole, 0', on the bearing 19, so that by turning the screw 0' the roll 1) may be adjusted to and from the roller 0. A set-screw, 8 may be employed for adjusting the roller g toward the roller 1'.

Over the frame formed by the rollers f 'L' p is tightly stretched a belt, 25, of absorbent materialsuch as felt-and over the frame formed by the rollers 76 m 0 is a similar belt, t. This gives two endless belts, t t, which are compelled to travel toward each other by the movement of the rollers 19' and 0, to soak up the necessary water or other fluid employed in dampening the articles. To secure a uniform quantity of moisture in the belts 25 t, and just the amount necessary to dampen the articles the proper degree, the roller m is forced against the roller Z, so that the excess of water will be squeezed out of the belt t, and the roller g is forced against the roller 2', which causes the excess of water to be squeezed from the belt If as it passes between the rollers g and i. If at any time the belts are not sufficiently tight on their frame of rollers, the difficulty maybe obviated by forcing the rollers p away from the roller i and the roller on from the roller 0 by the screws 9" and 8.

To drive the rollers in the proper direction with respect to each other, any suitable gearing may be employed. I have shown for this ironing-machine.

purpose each pair of rollers geared together, and on the outer ends of the rollers Z a" pinions it 11 which intermesh, and some one of the pinion-shafts being driven by a belt from some suitable motive power. This insures the positive rotation of all the'upper rollers of the frame supporting the bolts 15 t, and prevents the slipping of the latter, at the same time causing the belts to travel in opposite directions.

In operating the machine the collars or other articles to be dampened are passed between the surfaces of the belts it as they pass over the rollers 0 p, the latter being adjusted so that they are just the right distance apart to press the required amount of moisture from the belts t into the collar or other article as it is drawn through by the downward movement of the rolls and belt. The collars pass down through the slot 6 to a suitable receptacle, v, in which they can be conveyed to the As a number of collars and cu ifs can be passed through between the rollers 0 p at the same time and the apparatus works rapidly and requires but little skill in the operator, a very large amount of work can be performed by it in a comparatively short space of time.

Having now described my invention, what I claim is In a dampening-machine, the combination of the body a, having the tanks 0 0, one on each side of the same, belts t and t, of some absorbent material, mounted on a triangular frame of rollers, so that the belts dip down into said tanks, and the adjustable rollers for pressing the excess of moisture from said belts, substantially as and for the purpose set forth.

In testimony whereof I, the said JOSEPH M. JOHNSTON, have hereunto set my hand.

JOSEPH M. JOHNSTON.
